Shortage of natural resources is leading the construction sector towards an accelerated pace in the use of geosynthetics. However, misconceptions around their properties often obstruct the progression to environment-friendly solutions. Regarding the drainage of fluids, high-quality geocomposites provide not only better hydraulic performance than traditional solutions based on granular layers, but also lower installation costs. Moreover, when comparing the volumes and weights concerning both solutions, the logistical footprint is drastically reduced. Overall, drainage geocomposites emerge as a cost-effective solution against conventional designs and are presented to become a key player within a broad range of applications.
